Specication of Letters Patent. Patlliied Jlllle 6 1911.

Application led August 10, 1910. Serial No. 576,462.

ToaZZ whom it may concern: Be it known that I, CHARLES E. WHITE, a citizen of the United States, and a resident of the city and county of San Francisco and State ol California, have invented certain new and useful Improvements in Pumps, of which the following is a specification.-

The invention relates to internal combustion pumps wherein liquid is elevated by means of the expansive force of an exploded was. C One of the objects of the invention is to provide a pump of rthe character or type referred to in which the full static pressure of liquid in the discharge or delivery pipe is utilized for introducing an explosive charge into the combustion chamber and compressing it therein. further object of the invention is to provide means whereby the explosive charge is initiallydrawnl into a separate gas cham ber andV forced from such chamber to the` combustion chamber and compressed into the latter by the action or pressure of thej liquid in the discharge or delivery pipe, and further to utilize the pressure of the liquid in such discharge pipe as a means for operating the igniter by which the explosive charge in the combustion chamber is eX- ploded.

The device possesses other advantageous features which, with the foregoing, will be set forth at length in the following description, Where I shall outline in full that form or embodiment of my invention which I have selected for illustration nin the drawings accompanying and forming part of the present specification. From this it will be apparent vthat I do not restrict myself to the showing made by such dra-wings and descriptions as I may adopt many variations wlthin the scope and spirit of myinvention.

The accompanying drawing illustrates in vertical cross-section the pump adapted to be immersed in liquid, also showing the gas compression chamber and connectionsw with the combustion chamber and means for igniting the l The pump consists of the chamber 2 which is preferably cylindrical-in shape, but various modications of the chamber can be used "di, ,ured to the lower end of the chamber 2 a tee 3 having Va suction or supply pipe A checlevalve ,5 in this pipe allows the liquid to flow into the chamber 2 l'through a connection 18.

at the proper time. j Connected to the lother outlet of thetee 3 is a delivery pipe 6,

through `which the liquid is forced to a A-'similar check-valve 7 in higher level. this pipe'prevents the liquid from fiowing The liquid from the source of supply enters the chamber 2 through the supply pipe 4f, the

valve 5 operating to allow the entrance andI is discharged from the chamber 2 through the pipe 6, the valve 7 operating to allow the liquid to pass.

A vertical pipe 8 communicates with pipe 6 on the low pressure side of valve 7 having a closed upper end, which constitutes a gas chamber 9. Secured to the upper end of the gas chamber is a gas supply pipe 10, pr'of vided with a check-valve 11. A pipe 12 connects with the top of gas chamber 9 and the combustion chamber 2 and is provided Ywith a check valve 12, affording a connection between the gas )chamber and the combustion chamber for the purpose of conveying an explosive gas into the combustion chamber.

An exhaust valve casing 14 connects with the top of the combustion chamber 2 and also connects with the delivery pipe 19 interiorly provided with a cup 20 having a bored extension 21 which extends downwardly. Theupper end of the cup has a diaphragm 22 whichl closes the said upper end and the pipe 18 extends into the cup 20 The casing 14 isv at a point below the diaphragm. The bore of the pipe 18 is somewhat greater than the bore of the extension 21 so Lthat the rate of discharge will be lower than that of filling.

The diaphragm 22 is provided with a valve 23 to enter a seat 2li when the diaphragm movesupwardly. A vertical stem 25 is connected to the valve 23 and at its upper end is provided with a contact 26 of suilicient length to bridge the gap between the electric terminals 27 and 28 of the ignitionv device. When the cup 2O is empty and the diaphragm lowered the contact or circuit closer will be out of engagement with the terminals 27 and 28 and will so remain until the ating the exhaust valve 14C and closing the ignition circuit to the spark plug 16 at the proper time, and inthe drawing I .have

i `shown one such means, but it is to be understood that I do not limit myself to such means. The top of the combustion chamber 2 may be` inclosed in' a casing 17 to -protect the valves and the electrical sparkingdevice that the pump may be submerged in a. liquid to` any desirable depth.

The operation of the merged ina liquid and the cem ustion chamber is filled with liquid andan explosive gas, andthe delivery pipe 19, ipe 8 and chamber 49 are full of liquid; w en the circuit to the spark plug closes the explosion thereof forces t e liquid through the pipe 6; thisl .movement of the liquid closes the valve 5 and opens the valve 7 As the liquid moves through .the -pipe G'the liquid piston in pipe- 8 and chamber 9 will move'downwardly andv thereby create a suc- 4move toward pipe 19, thus removin Y so' tion in the. gas chamber 9, whereupon vthe valve l1 will open `and afresh supply of gas be drawn into the chamber 9 through the pipe 10.` As the liquid moves upwardly in the pipe 19 the liquid piston in pipe 18 willl -t e pressure from the diaphragm 22 an permitting the contact 26 to move downwardly. After the explosive force is spent, the action 'of the liquid in the deliver pipe 19 closes the valve 7 andthe liquid piston in the pipe. 8 and chamber 9 forces the explosive mixture from the chamber 9 -into the chamber 2. It will be observed that while this action is taking place the water will have risen in the' chamber 2 and above the lower end of the pipe 12, thus the gas will be compressed vprior to ignition, which latter will not be effected until the liquid piston in the pipe 18 forces the diaphragm upwardly as before described. It will be observed Whenthe diaphragm is lowered'to the position shown in the figure that the valve 23 is unseated to permit the products of combustion to escape through the o ening 30 in thecasing 14. It

` bustion chamber, thus utilizing a' high per# 55 I by Letters Patent is,
